IMPROVEMENT IN MACHINES FOR SPINNING WOOL.

Specification forming part of Letters Patent No. 120,255, dated October 24, 1871.

To all whom it may concern:

Be it known that I, LUTHER W. FELT, of Keene, in the county of Cheshire and State of New Hampshire, have invented certain Improvements in Machines for Spinning Wool, of which the following is a specification:

My invention relates, rst, to certain improve-- ments in the mechanism for imparting the primary twist to the roving, preparatory to its being drawn to the degree of iineness required for the inished yarn, secondly, it relates to certain improvements in the mechanism which gives the nal twist to the yarn and winds it on the bobbin;.and lastly, it relates to certain improvements in mechanismfor facilitating the operation of dofng. The general object of my invention is to produce a better quality of yarn, and todo the same much more rapidly than can' be done with the ordinary jack.

The following is an accurate description of i those parts of a spinning-machine which embody my invention, reference being made to the accompanying drawing, of which- Figure l is a transverse section or side elevation of a machine embodying my invention. Figs. 2, 3, and 4L are similar sections of the front parts of the same, showing parts in different positions. Figs. 5 to l5, inclusive, are details to be referred to.

A is the frame of the machine. I, Fig. l, is a brace or arm carrying a twisting-tube, K, to be turned by a belt passing over the pulley j'. Figs. 13,14, and l5 show the construction of the tube. InFig. I4, K is alight removable tube with a slit, j, extending through its entire length. It also has a wire, h, bent into a hook at one end and passing around the tube K', in the notch i, and formed into a spring, h', at the other end. The hook h, being made of spring wire, will retain its position upon the tube K by its own elasticity, upon being sprung around it, as before mentioned, without the aid of other devices. The form of the hook will he readily understood by reference to Figs. I4 and 15. In the latter figure the tube K is shown inserted in the driving-tube K. L L and M are drawing-rolls. N is a iiier, shown in Fig. 5. This flier consists of a tube, N, large enough to admit the bobbin freely without contact. The upper part of the tube N has an end piece, l, inserted, which has a projecting flange, and on one side a depression or notch, p, Figs. 5, 6, or 7. This notch p communicates on one side with a slit, 1^, in the tube N. The lower part of the dier consists of a wire, s, bent into a loop, and a hook, s'. Fig. 9 is a view of this wire s, seen partly from below. The end piece l of the-ilier has a conical depression, shown by dotted lines at m, Fig. 5, which depression leads to a rectangular opening, m', or hole of such shape and size as to nearly t closely the lattened end n of the spindle S, which end n is shown in Fig. 8. Fig. 6 shows the end piece l of the flier, seen from above, and Fig. 7 the same seen from below. The spindle S is supported by a sliding frame-work, O, shown in its highest position in Figs. l and 2. P is another fname, sliding in O and carrying a spool, T, which moves freely over the spindle S, but does not partake of the motion of the latter, except when the teeth or projections 3 on the spool T are allowed to engage wth the teeth or projections 4 on the larger part of the spindle S. Fig. 3 shows the teeth 3 and 4 thus in contact. Figs. I() and 1.1 show the spool T, in which l l are small projections from the spool T, which enter corresponding depressions in the bobbin R, and insure the motion of the spool T and the bobbin R together. V is a cross-piece hingedl at w to a bar, y, fastened to the frame l?. A projection, U, is attached to the cross-piece V, which projection carries a cam, W, turning on a pivot not concentric with the curved portion of the cam. X is a spring attached to the cross-piece V, pulling outward on a wire, 9, which passes and is attached to a yoke, Y, mounted on the lower part of the spool T. Fig. I() shows a side view of the yoke Y, and Fig l2 a view from above of a section of the same, made in the line w of Fig. 10. Y consists of two parts, which clasp the spool T, being hinged together by the wire 8 around the pins 7 7. The wire 9 passes from the spring X to the pin 7 on the opposite side, and the wire l0 crossing the wire 9 to and around the pin 7, is fastened at its other end to the frame P on the side opposite the spring X. The weight of the frame P and of what it carries is balanced by the weight z, both being suspended to the shaft and pulley Q. Z is a follower or wire to be used in dofling or changing bobbins.

The operation of these parts is as follows: As

the roving is delivered from the griping-wheels' D and E, (said wheels D and E being included in Letters Patent No. 103,858, dated June 7, 1870, already granted to me, and certain other parts attached to said wheels being included in-another application for a patent made simultaneously with this,) the roving is passed through the twisting-tube Kand around the hook h, so that it (the roving) is grasped rmly enough to insure its revolving with the tube and being twisted. Motion is given to the rolls L and L, upon which the roll M rests, and the roving is thereby grasped and drawn. The point ofthe hook h is brought as closely as practicable to the point of contact of the drawing-rolls L L with the roll M, so that the twist imparted to the roving by the twistingtube K is retained up to the point where the drawing-rolls are tangent toV each other, in order that the strength of the roving may be sufficient to insure its being drawn without breaking. From the drawing-rolls the roving passes down by or in the depression p in the end piece l, and through the flier by means of the slit r, to and around the wire s to the hook s', and thence to the bobbin R. When the frame O is in its highest position, so that the spindle S enters the hole m' of the end piece of the flier, and when the frame P is raised, bringing the bobbin R within the iiierN and releasing the teeth 3 of the spool T from the teeth 4 of the spindle, motion is given to the spindle by a belt passing over the pulley on its lower part, the spindle turns the iiier, and the yarn is spun and wound on the bobbin. The yarn is laid on the bobbin regularly in conical layers by mechanism not shown in the drawing. The tension of the yarn on the bobbin is regulated by the following means: In winding the yarn the frame P is alternately raised and lowered. When P is raised so as to cause the yarn to be wound on the larger part of the cone, as seen in Fig. 2, less strain is then exerted on the yarn; but the rise of the frame P and the friction of the cam W on the frame of the machine rolls the cam upward to the position seen in Fig. 2, when the cam pulls the frame or cross-piece V forward, and by the action of the spring X and yoke Y, pressure is exerted on the spool T, thus giving sufficient increase of tension to compensate for the difference of the size of the cone. When the frame P is again lowered so as to wind on the smaller part ofthe cone, as seen in Fig. l, the cam W is rolled back outward, the spring X is released, and by this alternate action the tension is made perfectly uniform.

If the roving breaks between the wheels D and E and the drawing-rolls, the removable tube K' is taken out of the main tube K, and the roving is passed through the tube K' by the slit j, and around the hook l1. under the spring h'. The tube K' is then replaced without having the machinery stopped. If the yarn is broken below the drawing-rolls the end is taken from the bobbin, passed around the wire s of the flier N, between s and and s', thence up through the slit r into the iiier, and is spliced with the roving next to the drawing rolls. The front of the frame-work in which .the flier N turns, is slotted to correspond with the slit r in the dier, so that the yarn is passed into the flier without removing the latter from the frame. A tube, 13, provided with a longitudinal slit or series of openings, 14, is placed just below and parallel with the drawing-rolls, from which a current or jets of air are made to issue behind the threads toward the front, so that if the yarn breaks the roving coming out from between the drawing-rolls may not be drawn around the lower roll, but be blown outward so as to be easily caught and spliced.

When the bobbins are full, the frame O is lowered so as to bring the upper end of the spindles below the lower end ofthe flier. The wire or follower Z is raised from the position shown in Fig. 3, over and just behind the upper end of the spindles. The frame OV is then raised, asV seen in Fig.V

3, and the frame P slightly lowered tovbring the teeth ofthe spool T and the spindle together, but not to engage the spindle with the iiier. The spindles are then turned backward to unwind a quantity of yarn, which is, at the same time, brought downward and backward by the wire or follower Z. A few turns of the spindles runs the yarn down off the bobbins to the spool T, thus securing the thread for the next bobbins. Fig. 4 shows this position of the wire Z and the yarn, and also the frames O and P tipped forward. The bobbins may now be pulled off, breaking the yarn, but leaving the end attached to the spool T. When the empty bobbins are put on, the frames are brought back to their erect position, the frame O is raised to its highest position so that the spindles may engage and turn the iliers, the frame P brings the bobbins within the fliers, and spinning recommences. The yarn immediately runs back from the spool T to the bobbin. The opposite sides of the upper flange of the spool T are removed, as seen at 2, Fig. ll, so that the accumulation of yarn on the spool may easily be cut off when desired.
